You definite articles and undefined of the Portuguese language (o, a, os, as, um, um, um, um), in english language are represented by only three articles: The, an and the and are always used in front of a noun.

Defined Articles

The defined articles (definite articles, in English) are used whenever we refer to something specific or that has already been mentioned in a previous speech.

In the English language, there is only one definite article, O the, which in addition to being used in front of singular nouns, is the only one that can be used in front of plural nouns.

In Portuguese, he is translated per O, The, you and at.

The car is new. (The car is new.)

It is assumed that the recipient of the message already knows which car you are talking about. It is implied that they have talked about this car before.

The postcards arrived today. (The postcards arrived today.)

Implicit in this sentence is the idea that whoever receives this message knows which postcards they are talking about. Furthermore, the fact that the word

postcards (postcards) being in the plural, only allows the use of the definite article the.

The backpack is blue. (The backpack is blue.)

The color (blue) specifies the noun (backpack), that is, it is not just any backpack, but the blue backpack. Also implicit here is the idea that this backpack has been mentioned before and for this reason, the message recipient knows which backpack is being talked about.

Sue is drinking an orange juice. The orange juice is cold. (Sue is drinking some orange juice. The orange juice is cold.)

In this case, the idea that the noun (orange juice) was mentioned before, and for this reason, it is already known which orange juice is cold: the orange juice Sue is drinking, not just any juice.

The girls are playing. (The girls are playing.)

The phrase refers to a specific group of girls, which has probably been mentioned before, who are playing and, furthermore, the fact that the word girls being in the plural, only allows the use of the definite article the.

Feline asthma [TO BE] a new disease. It was first described in scientific literature more than 90 years ago, says veterinarian Philip Padrid of the Family Pet Animal Hospital in Chicago.

Nicki Reed, a veterinarian at the University of Edinburgh's Hospital for Small Animals, says that when a coughing cat is brought to the clinic, she must first establish if [ARTICLE] cause is [ARTICLE] infection, asthma, or something more sinister, like a lung mass.

To do this, Reed usually performs an x-ray, takes a lung fluid sample, and conducts a bronchcoscopy _ an examination that uses a flexible microscope inserted into the cat's airway.

Most of the time, asthma is a mild disease, Reed says. But in some cases cat’s lungs collapse or their ribs fracture due to difficulty in breathing.

“I think if we can identify asthmatic cats quite early and get treatments on board to suppress their cough, then hopefully we can avoid them coming to such extremes,” she said.

Survival of the cutest

Thousands of creatures will disappear if we only focus on the most fascinating species.

The struggle to preserve the world's biodiversity is being compromised by fatal flaws in the way conservations draw up their lists of endangered species. An Australian botanist warms that the lists reflect the plants and animals that scientists are most interested in studying, rather than the most threatned species or those at risk of extinction. For instance, says Mark Burgman of the University of Melbourne, lists compiled and used by organizations such as the World Conservation Union (IUCN) and the Secretariat to the CITES agreement are heavily biased toward birds, mammals and flowering plants, to the detriment of less charismatic species such as insects and fungi. If no one tackles the problem, Burgman believes we will unwittingly focus our conservation efforts in the wrong places, and fail to stop the biggest mass extinction since dinosaurs. Rare species lists contain fewer threatened insects than birds, although we know of a million insect species and nearly fewer than 10,000 birds. That’s because most insects are poorly studied, says Burgman. For most, all that we have a specimen in a museum and a formal brief description, he says. Generally, little or nothing is known about their habitat and abundance, and no one may have looked for them since their discovery. “We assume all's well because we don't have any evidence, and we don't have evidence because we haven't looked”, Burgman says. Georgina Mace, director of science at the Zoological Society of London and chair of the Species Survival Committee, thinks Burgman has identified real problems. Yet she says that groups like the IUCN are addressing them. Starting with amphibians, it has begun assessing the global health of whole groups of related animals, species by species. Putting a species on the Red List is like assessing people coming into a hospital emergency room, she says. It's not a robust prediction of what will happen, but it's a quick way to pick out the sickest. But Burgman says that the criteria for assessing whether the species will go extinct vary from country to country and from study to study. He has compared a range of studies and found that different methods produce very inconsistent results. He says conservation scientists ―need to get our act together‖ and develop a uniform set of tools that everyone can test and agree upon. Even ―extinction‖ can be hard to define, he points out. A surprising number of species has been declared extinct, only to resurface later after people had given up looking for them.
